基本解釋

So, this is called back scattering.
這叫做背散射。
Based on the uniform geometrical theory of diffraction, the equivalent current is used to calculate the back scattering field for the finite cone.

What is new about Dr Cinzano's research, which is about to be published in the Monthly Notices of the Royal Astronomical Society, is that he and his colleagues have managed to take account of the effects of back-scattering by clouds and dust in the atmosphere, as well as the effects of the original sources of the light themselves.
ECONOMIST: Going, going, nearly gone
In his spare time he trained his instincts by field-stripping old watches, scattering the pieces, and teaching himself to put them back together like a jigsaw puzzle.
